Abstract
A detent hinge firmly secures the door of a containment system in an upward position, downward position, and optionally at pre-determined positions therebetween. The hinge generally includes two hinge assemblies each including a leaf and one or two knuckles, with the knuckles of both assemblies aligned end-to-end. The two hinge assemblies are independently rotatable relative to each other but share a rotational axis. The hinge is locked and the door is substantially immovable due to a spring-activated cam that impedes rotation of the hinge assemblies relative to each other. The hinge is unlocked by depressing a plunger which repositions the cam such that the hinge assemblies can freely rotate relative to each other, and the door can be raised or lowered.
